You are right, of course about 50hz vs 60hz, but some were posting about running a 110v 60hz line in Australia. Unless I am sadly mistaken, or they are running solar or a generator, 60hz ain't gonna happen.
And when I lived in Europe I never saw a 110v power tool in local use. GIs. maybe, but not the natives.

60Hz is only needed for electric motors of some TTs. Luckily those TTs use very cheap motors which could be changed for a few pounds.
50 or 60Hz makes no difference at all for something like an amplifier since the PSU rectifies it into DC anyway.
As for 110V transformers: There are a few hundred on ebay uk at any one time starting at £0.99 for a 3.3 KVA unit right now. Plenty of them in use on every building site I've ever been to.
Pretty much every US act which brings their own backline uses them for their guitar amps and such.
The problem lies not with the actual mains voltage - easily fixed with a step-down transformer - it's with the 60Hz power transformer in the stereo components.
Transformers made for 240v/50Hz will function quite happily at 110v/60Hz - providing a suitable 110v --> 240v step-up trannie is provided.
However, transformers made for 60Hz get hot when they're connected to a 50Hz mains - even though a 240v --> 110v step-down trannie is provided.

Friends of mine moving to South America from the US got a big PS Audio power re-generator. It worked beautifully. Of course their big model will set you back $5k, so it ain't cheap.

Wow, thanks bl.zeebub. So one of those £0.99 110V transformers and the correct plug adapter to fit an Aussie outlet and I'd be good to go, say, plugging in and running a 6x200 watt 6 channel Home theater amp I have?

I would have thought so.
